384GB DDR5 RDIMM Kit

This NEMIX RAM kit provides 384GB of DDR5 memory in a matched set of four 96GB modules. Each module is a 288-pin Registered DIMM operating at 6400MHz with a CAS latency of CL52 and a voltage of 1.1V. It is designed specifically for the Supermicro H14SSL-N motherboard.

Target Server Builds

The kit suits administrators upgrading a Supermicro H14SSL-N system that requires Registered ECC memory and supports the 2Rx4 rank configuration. It is not for systems that accept only unbuffered UDIMMs or SODIMM form factors, nor for platforms limited to lower maximum capacities per slot.

Registered ECC Architecture

The registered buffer reduces electrical load on the memory controller, allowing all four slots to run fully populated at the rated 6400MHz speed. ECC functionality detects and corrects single-bit errors to maintain data integrity in production workloads.

Questions about this item

What speed does the DDR5 6400 interface actually deliver on this Supermicro H14SSL-N kit?

The kit runs at DDR5 6400 (PC5-51200) with CL52 latency at 1.1 V, matching the motherboard's rated speed when all four slots are populated.

What physical slot and form factor do these 96 GB modules need on the H14SSL-N?

Each module is a 288-pin registered RDIMM; the board requires RDIMMs — not UDIMMs or SODIMMs — and the kit fills four DIMM slots.

How should the four 96 GB RDIMMs be installed, and what step is often missed?

Follow the motherboard manual's exact population order for four dual-rank modules; skipping the prescribed slot sequence is the common error that prevents full 384 GB recognition.
